Virtualization and physical resources
Hello everyone
I would like to hear your opinions about virtualization and physical resources
On aix we can create micropartitions with virtual ethernet and scsi resources. We can move partitions on line with partition mobility (here all have to be virtual).
But hear I have a comment. Best practices say that production environment has to be physical, disk, ethernet and with another server exactly like the first one in case the first one fails.
Then I think maybe one option could be that partitions production line be physical and maybe test partitions or maybe develop partitions line could be virtual.
What do you think ?????
What could be the good and bad things about virtualization against physical.
Thanks for your comments
Greetings

hv_utils
HYPER-V(4) BSD Kernel Interfaces Manual HYPER-V(4)
NAME
hv_utils -- Hyper-V Utilities Driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in the system kernel configuration file:
device hyperv
DESCRIPTION
The hv_utils driver provides time keeping, shutdown and heartbeat functionality for FreeBSD guest partitions running on Hyper-V. Hyper-V is
a hypervisor-based virtualization technology from Microsoft. The hv_utils driver is one of the core drivers required to be present in guest
partitions running on Hyper-V. This driver provides the following functionalities to guest partitions:
(a) Time Keeping: The clock inside the guest partition will remain accurate by synchronizing to the clock on the virtualization server via
Timesync service, and with the help of the pluggable time source device.
(b) Integrated shutdown: Guest partitions running FreeBSD can be shut down from Hyper-V Manager console by using the "Shut down" command.
(c) Heartbeat: This feature allows the virtualization server to detect whether the guest partition is running and responsive.
SEE ALSO
hv_ata_pci_disengage(4), hv_netvsc(4), hv_storvsc(4), hv_vmbus(4)
HISTORY
Support for hv_utils first appeared in FreeBSD 10.0. The driver was developed through a joint effort between Citrix Incorporated, Microsoft
Corporation, and Network Appliance Incorporated.
AUTHORS
FreeBSD support for hv_utils was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>.
